Ce0.8Y0.2O2-δ-BaCe0.8Y0.2O3-δ Dual-Phase Hollow Fiber Membranes for Hydrogen Separation

open access: yesInorganics, 2023
Partial oxidation of methane (POM) is a prominent pathway for syngas production, wherein the hydrogen in syngas product can be recovered directly from the reaction system using a hydrogen (H2)-permeable membrane.

Phenomenological description of phase inversion

open access: yesPhysical Review E, 2009
We propose an extended Ginzburg-Landau model for a description of the ambivalence region associated with the phenomenon of phase inversion observed in dispersed water-oil flow through a pipe. In analogy to the classical mean-field theory of phase transitions, it is shown that a good quantitative representation of the ambivalence region is obtained by ...

Fluid dynamics of the phase inversion process in the bulk polymerization of high impact polystyrene [PDF]

open access: yes, 2021
"In the synthesis of HIPS, phase inversion (PI) is the critical point at which a dispersed PS-rich phase becomes a continuous matrix, leaving behind a PB-rich phase as dispersed particles that may contain occluded PS-rich droplets inside (occlusions ...

Polydopamine functionalized halloysite nanotubes incorporated polyethersulfone hollow fiber membranes for the removal of arsenic (as-v) from water [PDF]

open access: yesAdvances in Environmental Technology
Polyethersulfone (PES) based hollow fiber membranes containing polydopamine-functionalized halloysite nanotubes (FHNTs) were fabricated in different concentrations employing a dry-wet approach and using phase inversion methodology.

Global crustal thickness from neural network inversion of surface wave data [PDF]

open access: yes, 2007
We present a neural network approach to invert surface wave data for a global model of crustal thickness with corresponding uncertainties. We model the a posteriori probability distribution of Moho depth as a mixture of Gaussians and let the various ...

Experimental Investigation of Phase Inversion of Liquid-Liquid Systems in a Spray Extraction Column [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 2008
An experimental study of the phase inversion behavior of liquid-liquid dispersion has been conducted in a spray extraction column for systems of toluene / water, n-hexane/water, CCl4/water, toluene /water + glycerol (25 % wt), toluene + CCl4 (25 % wt ...
